Question

19x{1+E3)}=19x7t19x (-3)​

Answer 1

Answer:

the local body that provides different services to the people in big cities is called dash

Step-by-step explanation:

If asin² (x) + bcos² (y) = c, bsin² (y) + acos² (y) = d and atan (x) = btan (y)

Then prove that : a²/b² = (d - a) (c - a)/(b - c) (b - d)

solve by eliminating x and y.
